DETAILED DESCRIPTION OF THE INVENTION

For the sake of the advantages, spirits and features of the presentinvention can be understood more easily and clearly, the detaileddescriptions and discussions will be made later by way of theembodiments and with reference of the diagrams. It is worth noting thatthese embodiments are merely representative embodiments of the presentinvention, wherein the specific methods, devices, conditions, materialsand the like are not limited to the embodiments of the present inventionor corresponding embodiments. Moreover, the devices in the figures areonly used to express their corresponding positions and are not drawingaccording to their actual proportion.

Please refer to FIG. 1 . FIG. 1 is a function block diagram illustratinga luminous device 1 according to one embodiment of the presentinvention. As shown in FIG. 1 , the luminous device 1 includes acontrolling device 11 and a plurality of luminous modules 12. Thecontrolling device 11 is electrically connected to the luminous modules12 and configured to send a power signal to the luminous modules 12,wherein the power signal includes a selecting signal and a luminoussignal. The luminous module 12 (such as 12A and 12B) includes a drivingchip 121 and a LED chip 122 connected to the driving chip 121. Inpractice, the controlling device 11 is electrically connected to theplurality of luminous modules 12 in series or parallel. The controllingdevice 11 can include a controlling chip integrated with the circuitboard 2, and the controlling device 11 can be configured on the circuitboard 2 to send the power signal. The luminous module 12 can include thecircuit board, and the driving chip 121 and the LED chip 122 areconfigured on the circuit board. The driving chip 121 can be a drivingIC, and each driving chip 121 of the luminous modules 12 has anidentifying code different from others. In practice, the luminouselement of the luminous module 12 is not limited to one LED chip 122.The luminous module 12 can also include a plurality of LED chips (theLED chips can respectively emit lights with different colors, such asred, green and blue LED chips).

As mentioned above, the power signal includes the selecting signal andthe luminous signal, and the luminous signal further includes a colorcode information. In practice, the selecting signal can be a signalmatching the identifying code of the driving chip 121 of the luminousmodule 12, and the color code information can be a signal determiningthe light emitting or color scale of the LED chip 122 of the luminousmodule 12. The selecting signal of the power signal can be locatedbefore the luminous signal. That is to say, when the controlling device11 sends a set of power signal, the controlling device 11 sends theselecting signal first, and then sends the luminous signal including thecolor code information. The selecting signal and the luminous signal canbe formed of at least one binary bit signal (1/0), and the lengths ofbit signals of the selecting signal and the color code information canbe different. For example, as shown in FIG. 1 , the number of theluminous modules 12 is 2, and the number of the LED chip 122 of eachluminous module 12 is 1. When the binary code of the selecting signalcorresponding to the driving chip 121 of the first luminous module 12Ais “0” and the binary code of the selecting signal corresponding to thedriving chip 121 of the second luminous module 12B is “1”, thecontrolling device 11 can send the selecting signal with binary code “0”or “1” to control the LED chip of the first luminous module 12A or thesecond luminous module 12B to emit light. Since each driving chip 121 ofthe luminous modules 12 has the identifying code different from others,the number of the selecting signals sent by the controlling device 11can be 2 or more to recognize and control the luminous modules 12 whenthe number of the luminous modules 12 is greater than 2.

The selecting signal and the luminous signal of the power signal can beformed of data frame. The data frame comprises three parts: header, LEDcolor scale and ending code, wherein the header is aforementionedselecting signal, and the LED color scale is aforementioned color codeinformation. In this embodiment, the header and the LED color scale areformed of 8 bits, and the ending code is formed of 1 bit. Therefore, thedata length of the data frame is 8 bits+8 bits+1 bit. When thecontrolling device 11 sends the power signal to the plurality ofluminous modules 12 and the identifying code of any driving chip 121 ofthe luminous modules 12 matches the header of the power signal, thedriving chip 121 matching the header determines the illuminatingbrightness of the LED chip 122 according to the LED color scale of thepower signal and drives the LED chip 122 to emit light. For example, theidentifying code of the driving chip 121 of the first luminous module12A is “00100000”. When the power signal sent by the controlling device11 includes the header with “00100000” and the color scale with“00000101”, the driving chip 121 having the identifying code “00100000”drives the LED chip 122 to emit light with the brightness of the LEDcolor scale “00000101”. The illuminating brightness of the LED chip 122will be described later. It is worth noting that the number of theluminous modules 12 in FIG. 1 is, but not limited to, 2. The number ofthe luminous module 12 can be 1 or more than 2, and the number of LEDchips 122 of each of luminous modules 12 can over than 1, such as red,green and blue LEDs.

Please refer to FIG. 2 , FIG. 3 and FIG. 6A. FIG. 2 is a function blockdiagram illustrating a luminous module 12 according to one embodiment ofthe present invention. FIG. 3 is a structural schematic diagramillustrating the luminous module 12 of FIG. 2 . FIG. 6A is a datastructural schematic diagram illustrating the data frame according toone embodiment of the present invention. The number of the LED colorscales of the data frame can be corresponding to that of the LED chips.In practice, the number of the LED chip 122 of the luminous module 12can be 1 or more than 1. Each of the LED chips 122 emits light with thewave length different from others. That is to say, each of the LED chips122 emits light with the color different from others. As shown in FIG. 2and FIG. 6 , when the number of LED chips 122 is 3 and the LED chips arered LED chip 122R (the wave length is between 620˜750 nm), green LEDchip 122G (the wave length is between 495˜570 nm) and blue LED chip 122B(the wave length is between 450˜495 nm), the power signal sent by thecontrolling device 11 includes the LED color scale with three colors andthe three colors of the LED color scale are sent to the same luminousmodule 122. At this time, the data length of the data frame is 8 bits+8bits*3+1 bit. In FIG. 6 , “D0˜D7” means the bit numbers of the selectingsignal, “R0˜R7” means the bit numbers of the red LED chip 122R, “G0˜G7”means the bit numbers of the green LED chip 122G, “B0˜B7” means the bitnumbers of the blue LED chip 122B, and “end” means the bit number of theending code. When the identifying code of the driving chip 121 matchesthe header of the power signal, the driving chip 121 respectively drivesthe red LED chip 122R, the green LED chip 122G and the blue LED chip122B to emit light according to the LED color scales of three colors.

In this embodiment, the LED color scale is sent to the luminous module12 with 8 bit binary signal to enable the corresponding LED chip togenerate the luminous intensity with 256 scales, but it is not limitedthereto. In another embodiment, the LED color scale can be the colorcode information generated by the color code with other system (such asoctal and hexadecimal), and the luminous module 12 further includes acolor code transducer (not shown in the figure). The color codetransducer of the luminous module 12 transforms the LED color scalesinto the corresponding binary color scale values corresponding to thered LED chip 122R, the green LED chip 122G and the blue LED chip 122Brespectively when the LED color scales are sent to the luminous module12, and the driving chip 121 drives the red LED chip 122R, the green LEDchip 122G and the blue LED chip 122B to emit light according to each ofthe color scale values. In another embodiment, the data structure of thedata frame is not limited to be arranged in the order of the selectingsignal, the color code information, and the ending code. The order ofthe data structure of the data frame can be changed. Therefore, thedriving chip 121 with the identifying code matching the selecting signaldrives the LED chip 122 to emit light according to the color codeinformation when the luminous module 12 receives the data frame.

Please refer to FIG. 1 and FIG. 6B. FIG. 6B is a data structuralschematic diagram illustrating the plurality of data frames according toone embodiment of the present invention. In addition to the combinationof a single selecting signal and a single luminous signal or thecombination of a single selecting signal and a plurality of luminoussignals, the power signal also can include a set of predeterminedselecting signals and a set of luminous signals. As shown in FIG. 6B,the set of predetermined selecting signals includes a plurality ofselecting signals, and each selecting signal is corresponding to atleast one luminous signal of the set of luminous signals. When thecontrolling device 11 sends the power signal having the set ofpredetermined selecting signals and the set of luminous signals to theluminous modules 12, the driving chip 121 matching the selecting signalof the set of predetermined selecting signals drives the luminousmodules 12 to emit light according to the luminous signal correspondingto the selecting signal. In practice, the set of predetermined selectingsignals can include a first selecting signal, a second selecting signaland a third selecting signal, and the set of luminous signals caninclude a first luminous signal, a second luminous signal and a thirdluminous signal. The arranged sequence of the selecting signals and theluminous signals in the power signal sent by the controlling device 11can be the first selecting signal, the first luminous signal, the secondselecting signal, the second luminous signal, the third selecting signaland the third luminous signal. Therefore, the first driving chip of thefirst luminous module 12A matching the first selecting signal drives thefirst luminous module 12A to emit light according to the first luminoussignal after the first selecting signal when the controlling device 11sends the power signal to the luminous modules 12. Moreover, thecontrolling device 11 also can send the set of predetermined selectingsignals of the power signal first, and then send the set of luminoussignal, wherein the arranged sequence of all luminous signals iscorresponding to that of all selecting signals. For example, in thepower signal sent by the controlling device 11, the first selectingsignal is located on the first position of the set of predeterminedselecting signals, and the first luminous signal corresponding to thefirst selecting signal is located on the first position of the set ofluminous signals. Therefore, when the identifying code of the firstdriving chip of the first luminous module 12A matches the firstselecting signal located on the first position of the set ofpredetermined selecting signals, the first driving chip drives the firstluminous module 12A to emit light according to the first luminous signalcorresponding to the first selecting signal.

In one embodiment, when the controlling device 11 sends the power signalincluding a set of predetermined selecting signals and a set of luminoussignals to the luminous modules 12 and each of the selecting signals andthe luminous signals are arranged in sequence, the driving chip 121matching the selecting signal sequentially drives the luminous modules12 to emit light according to the color code information of the luminoussignals. For example, when the controlling device 11 sends the powersignals in the order of a first luminous module 12A, a second luminousmodule 12B and a third luminous module (not shown in figure), thedriving chips of the first luminous module 12A, the second luminousmodule 12B and the third luminous module sequentially drive a first LEDchip 122A, a second LED chip 122B and a third LED chip 122C to emitlight according to the selecting signal matching the identifying code ofthe driving chip 121 and the luminous signal of the power signal, so asto generate a sequentially lighting mode. The sequentially lighting modeof this embodiment can be the lighting mode for the luminous modules 12or for the LED chips 122 in the luminous module 12. Moreover, thelighting color in the sequentially lighting mode of the luminous module12 can keep the same, or change with the sequence. In practice, thelighting mode is not limited to the sequentially lighting mode andsimultaneously lighting mode. The lighting mode also can be acombination of flashing, eternal lighting, fade out, simultaneouslighting and sequential lighting.

Please refer to FIG. 1 , FIG. 4 and FIG. 7 . FIG. 4 is a schematicdiagram illustrating the waveforms of the luminous signal according toone embodiment of the present invention. FIG. 7 is a signal dataschematic diagram illustrating the positional code information accordingto the embodiments of the present invention. The luminous device 1 ofthe present invention can further include a battery 3. The battery 3 iselectrically connected to the circuit board 2 to provide power to thecontrolling device 11. When the controlling device 11 sends the powersignal to the luminous module 12, the controlling device 11 can load theselecting signal and the luminous signal into the power signal throughthe power provided by the battery 3 and send the power signal to theluminous module 12 to make the LED chip 122 emit light. In practice, thebattery 3 can be a primary cell such as heavy duty, alkaline battery andso on, and can be a secondary battery such as rechargeable battery.Furthermore, the battery 3 can be a rechargeable battery with a USBport. In one embodiment, the battery 3 provides a DC voltage, and thecontrolling device 11 loads the selecting signal and the luminous signalinto the DC voltage (such as 1.8V, 2V or 2.2V) to form the power signal.At this time, the power signal comprises bit signals with differentvoltage values. As shown in FIG. 4 , the horizontal axis means time (T),and the vertical axis means the voltage (V). In this embodiment, a bitsignal can be formed of a waveform, and the waveform includes a peakzone (t1˜t2 in the waveform) and a base zone (t2˜t3 in the waveform).Wherein, the peak zone voltage value (VH) is greater than the base zonevoltage value (VL). Moreover, the base zone voltage value is greaterthan the grounding voltage value. In practice, the peak zone voltagevalue of the waveform can be between 3V and 6V, and the base zonevoltage value of the waveform can be between 1.8V and 2.5V, but it isnot limited thereto. Therefore, the power signal is formed of aplurality of waveforms with different voltage values. Furthermore, thepower signal includes the header formed of a plurality of waveforms, theLED color scale formed of the plurality of waveforms, and the endingcode formed of at least one waveform.

In general, the binary codes of the digital signals can be distinguishedfrom each other by the wave peaks and wave troughs of the waveform. Thewave peak is determined as “1” of the binary code when the waveform ofthe digital signal is at the wave peak with the voltage value, and thewave trough is determined as “0” of the binary code when the waveform ofthe digital signal is at the wave trough of the grounding terminal.However, in another embodiment, the binary code “1” or “0” of the bitsignal is not determined by the wave peak or wave trough of the waveformto determine, but by the time length of the waveform of the bit signalin the base zone. As shown in FIG. 4 , the first bit signal S1 includesthe peak zone t1˜t2 and the base zone t2˜t3, and the second bit signalS2 includes the peak zone t5˜t6 and the base zone t6˜t7. Wherein, thetime length of the peak zone t1˜t2 of the first bit signal S1 is thesame as that of the peak zone t5˜t6 of the second bit signal S2, and thetime length of the base zone t2˜t3 of the first bit signal S1 isdifferent from that of the base zone t6˜t7 of the second bit signal S2.In one embodiment, the bit signal is determined as “1” of the binarycode when the time length of the base zone in the bit signal is greaterthan a predetermined time length. On the contrary, the bit signal isdetermined as “0” of the binary code when the time length of the basezone in the bit signal is smaller than the predetermined time length.For example, when the predetermined time length is 8 μs, the time lengthof the base zone t2˜t3 of the first bit signal S1 is 12 μs, and the timelength of the base zone t6˜t7 of the second bit signal S1 is 6 μs, thefirst bit signal S1 is determined as “1” of the binary code and thesecond bit signal S2 is determined as “0” of the binary code. In oneembodiment, the binary code of the bit signal is determined by the ratioof time length of the base zone and the peak zone. For example, if thetime length of the peak zone is 4 μs and the time length of the basezone is between 2 and 4 times of that of the peak zone (such as the timelength of the base zone is between 9.5 μs and 15.5 μs), the bit signalis determined as “1” of the binary code. If the time length of the basezone is between 1 and 2 times of that of the peak zone (such as the timelength of the base zone is between 4.5 μs and 7.5 μs), the bit signal isdetermined as “0” of the binary code. However, in practice, the multipleof time length of the base zone and the peak zone in the binary signalis not limited thereto.

As shown in FIG. 7 , the bit signal of the power signal is formed aseight signal data consisting of “1” and “0” after being transformed asthe binary code. In practice, when the serial number of the selectingsignal is 008, the converted binary code of the selecting signal ispresented in the order of “00010000”. In one embodiment, the selectingsignal can be a decimal value and each bit of the signal data can be avalue respectively (such as DO to D7 respectively mean the values of 1,2, 4, 8, 10, 20, 40 and 80), and the signal data is transformed as thebinary value according to the data code information. For example, whenthe value of the selecting signal is 021, the converted binary signaldata is “10000100”, and the driving chip 121 of the luminous module 12compares the converted signal data of the selecting signal with theidentifying code. The driving chip 121 drives the LED chip to emit lightaccording to the converted signal data of the color code informationwhen the comparison result is the converted signal data matching theidentifying code. It is worth noting that FIG. 7 only shows theconverted signal data of the selecting signal, and the converted signaldata structure of the color code information can be the same as that ofthe selecting signal.

In practice, when the controlling device 11 sends the power signalincluding the plurality of waveforms, the driving chip 121 of theluminous module 12 transforms the waveforms into the binary codesaccording to the time length of the base zone of each waveform in powersignal. The driving chip 121 with the identifying code matching theconverted binary selecting signal further drives the LED chip 122 toemit light according to the binary color code information and the powerof the power signal.

As shown in FIG. 4 , both voltage values of the base zones in the firstbit signal S1 and the second bit signal S2 are greater than the voltagevalue of the grounding terminal (the voltage value is 0). In thisembodiment, the driving chip of the luminous module transforms thewaveforms of the power signal into the binary codes and drives the LEDchip to emit light by the power of the waveforms when the controllingdevice sends the power signal to the luminous module. Since the LED chipemits light by the current and current value can be calculated by thecolor code information, the driving chip determines the illuminatingbrightness of the LED chip according to the current value calculated bythe color code information. For example, the maximum current requiredfor the LED chip is 6 mA, and when the brightness ratio of the colorcode information is 50% of the maximum brightness of the LED chip, thedriving chip drives the LED chip to emit light by a current of 3 mA.

Please refer to FIG. 2 and FIG. 3 again. As shown in FIG. 3 , theluminous module 12 can include a driving chip 121 and a plurality of LEDchips. In one embodiment, the driving chip 121 can include a power pin1211, a ground pin 1212 and a plurality of LED pins. The power pin 1211is configured to receive the power signal. The ground pin 1212 isconfigured for grounding. Each of the LED pins can be connected to theLED chips respectively. Each of the LED chips includes a LED power pinand a LED ground pin. Each of the LED power pins is correspondinglyconnected to each of the LED pins of the driving chip 121, and the LEDground pins are connected to the ground pin 1212 of the driving chip121. The driving chip 121 and the LED chips can be contained in apackage body. In practice, the power pin 1211 of the driving chip 121receives the power signal when the controlling device sends the powersignal to the luminous module 12, and the driving chip 121 selectivelydrives the LED chips to emit light according to the color codeinformation of the power signal. Since the LED ground pin of the LEDchip is connected to ground, the voltage difference can be selectivelyformed between the LED power pin of each of LED chips and LED ground pinaccording to the color code information when the driving chip 121 sendsthe power signal to the LED chips. The potential difference leads thecurrent to pass through the LED chips to make the LED chip to emitlight, and the package body can be an IC case to contain and seal thedriving chip 121 and the LED chips.

In one embodiment, the luminous module 12 can include a storage unit.When the controlling device sends the power signal to the luminousmodule 12, the luminous module 12 stores the power to the storage unit,and then, the driving chip 121 drives the red LED 122R, the blue LED122B and the green LED 122G according to the color code information. Inpractice, the storage unit can be a capacitance.

Please refer to FIG. 1 , FIG. 4 and FIG. 5 . FIG. 5 is a circuit diagramillustrating the luminous device 1 according to one embodiment of thepresent invention. It is worth noting that the luminous module 12 ofFIG. 5 is simply illustrated with only one LED symbol. Moreover, in FIG.5 , LDO is a linear regulator, R1 to R3 are resistances, and JP1 and JP2are connectors. These aforementioned components in FIG. 5 are thecomponents of the prior art, and their functions would not be describedherein. As shown in FIG. 5 , a signal point A is located between thecontrolling device 11 and the first connector JP1, and the controllingdevice 11 sends the power signal to the first connector JP1 through thesignal point A. Then, the power signal is sent from the first connectorJP1 to the second connector JP2, and the plurality of luminous modules12 connected to the second connector JP2 emit light according to thepower signal. When the controlling device 11 generates the power signal,the controlling device 11 can generate the base value and the peak valueof the bit signal by the circuit paths connected to the pin b3 and pinb4 respectively, and the power signal can be formed of the combinationof outputs of the pin b3 and pin b4. Therefore, the power signal can beformed on the signal point A according to the combination of the orderand number of the signals generated by the pin b3 and pin b4 of thecontrolling device 11.

The controlling device can be connected to the plurality of luminousmodules 12 in parallel. In one embodiment, all of the driving chips 121of the luminous modules 12 receive the selecting signal and the luminoussignal of the power signal when the controlling device 11 sends thepower signal to the luminous modules 12. In practice, when theidentifying code of one of the driving chips 121 matches the selectingsignal of the power signal, this driving chip 121 transforms the colorcode information of the luminous signal into the binary code and drivesthe LED chip 122 to emit light. When the identifying code of the drivingchip 121 does not match the selecting signal of the power signal, thisdriving chip 121 does not drive the LED chip 122 to emit light. Inanother embodiment, the driving chips 121 of the luminous modules 12only receive the selecting signal of the power signal when thecontrolling device 11 sends the power signal to the luminous modules 12.In practice, when the identifying code of one of the driving chips 121matches the selecting signal of the power signal, the driving chip 121receives the luminous signal of the power signal and drives the LED chip122 to emit light according to the color code information of theluminous signal.

Since the luminous module 12 emits light with different lighting modesthrough the controlling device 11 continuously sending the data frames,the power signal sent by the controlling device 11 is a plurality ofdata frames. In addition to the selecting signal and the luminoussignal, the data frame sent by the controlling device 11 also includesthe ending code. In practice, the ending code can be a bit signal,wherein the time length of the peak value of the ending code is the sameas that of the other bit signals but the time length of the base valueof the ending code is greater than that of the peak value. Therefore,the driving chip 121 of the luminous module 12 can discriminate each ofthe data frames according to the time length of the base value of theending code when the controlling device 11 sends the power signalincluding the data frames. In another embodiment, the time length of thepeak value of the ending code is smaller than that of the other bitsignals (such as ⅓ of the time length). Therefore, the driving chip 121can discriminate each of data frames according to the ending code havingshorter time of the peak value.

In another embodiment, the luminous module 12 can further include acounter (not shown in the figure), and the counter is electricallyconnected to the driving chip 121. The counter is configured to countthe number of the bit signal. In practice, the controlling device 11sends the power signal including 8 bits selecting signals and 8 bitscolor code information. The counter classifies the first 8 bit signalsinto a first signal block and classifies the last 8 bit signals into thesecond signal block after receiving the power signal. The counterreturns to zero after classifying the second signal block. Therefore,the driving chip 121 can recognize the selecting signal and the luminoussignal according to the first signal block and the second signal blockclassified by the counter, and can discriminate each of data framesaccording to the counter returning to zero.

The controlling device 11 sends the powersignal with the first lighting mode to the luminous module 12 accordingto the controlling signal to drive the luminous module 12 to emit lightwith the first lighting mode. Then, the motion sensor 14 generates acontrolling signal again when the motion sensor 14 detects the externalforce applied on the luminous device 1 again, and the controlling device11 sends the power signal with the second lighting mode to the luminousmodule 12 according to the controlling signal to drive the luminousmodule 12 to emit light with the second lighting mode.

In other one embodiment, the controlling device 11 sequentially sendsthe lighting modes of the power signal stored in the storage unit 13according to the controlling signal generated by the motion sensor 14.In practice, the motion sensor 14 sends a controlling signal to thecontrolling device 11 when the motion sensor 14 detects the externalforce applied on the luminous device 1.

In one embodiment, the switch 15 iselectrically connected to the controlling device 11 and the battery 3that provides the power of the controlling device 11. When the switch 15is turned on, the switch 15 allows the controlling device 11 to send thepower signal having the power provided by the battery 3 to the luminousmodule 12 to make the luminous module 12 to emit light. When the switch15 is turned off, the switch 15 blocks the battery 3 from providing thepower to the controlling device 11 to make the controlling device 11 notto send the power signal. In another embodiment, the switch 15 isconnected to the motion sensor 14 and the controlling device 11. Whenthe switch is turned on, the switch 15 allows the controlling device 11to send the power signal according to the controlling signal sent by themotion sensor 14 to the luminous module 12 to make the luminous module12 to emit light.
